May 9 (Reuters) - Duke Energy Corp (DUK.N) on Tuesday missed Wall Street estimates for first-quarter profit, as the gas and electric utilities firm was hit by unfavorable weather, higher interest expenses, and lower volumes.
Warmer-than-normal weather in the states serviced by the company weighed on customers' electricity needs for heating in colder months.
Duke's electric utilities, which serve 8.2 million customers in North Carolina, South Carolina, Florida, Indiana, Ohio and Kentucky, saw income fall about 12% to $791 million from last year.
Meanwhile for its gas utilities, which serve 1.6 million customers in North Carolina, South Carolina, Tennessee, Ohio and Kentucky, income rose about 13% to $287 million for the quarter, aided by better retail margins.
Duke said it earned $1.20 per share, on an adjusted basis, in the January-March quarter.
